did the mother belong to the teacher’s union?
No idea. She did not work at that school. Union has nothing to do with this, and should shut the hell up about it, unless the union starts saying proactive things, like “we’re going to teach defense, we’re going to press for more security, etc.” This guy just thought “oh, great, another opportunity to stick it to the gun owners”, right when our state is considering making our gun-free zones exempt for CPL holders.
